Answer: A) 10$ B) 5 days

Step-by-step explanation:

A) If you deposit 5 dollars per day for five days, you can show this by 5 x 5 = $25. If you account currently has -$15 and you are adding $25, you will have $10.

B) If you now have $10 after you made all you deposits, you will need 5 days to withdraw $2 from your account until $0. This is because you can equally divide $10 / $2 to equal 5 days.

Activity Give the exponential model for the following situation

Otrada [13]

Answer:

Suppose that a couple invested $50,000 in an account when their child was born, to prepare for the child's college education. If the average interest rate is 4.4% compounded annually, ( A ) Give an exponential model for the situation, and ( B ) Will the money be doubled by the time the child turns 18 years old?

( A ) First picture signifies the growth of money per year.

( B ) Yes, the money will be doubled as it's maturity would be $108,537.29.

a = p(1 + \frac{r}{n} ) {}^{nt}a=p(1+

)

a = 50.000.00(1 + \frac{0.044}{1} ) {}^{(1)(18)}a=50.000.00(1+

0.044

)

(1)(18)

a = 50.000.00(1 + 0.044) {}^{(1)(18)}a=50.000.00(1+0.044)

(1)(18)

a = 50.000.00(1.044) {}^{(18)}a=50.000.00(1.044)

(18)

50,000.00 ( 2.17074583287910578440507440 it did not round off as the exact decimal is needed.

a = 108.537.29a=108.537.29

Which number sentence is true?

Alexxx [7]

Answer:

The answer is B

Step-by-step explanation:

Because A is incorrect because the -8.9 is in absolute value which mean it will be an 8.9 which is greater than 5.6

C is Incorrect because - 5.6 is not greater than the absolute value of -8.9 which is 8.9, as you can see is greater than -5.6

D is incorrect because the absolute value of 5.6 is still 5.6 and the absolute value of - 8.9 is 8.9 which is greater that 5.6

<h2>B is correct because the absolute value of -5.6 is 5.6 which makes it less than the absolute value of -8.9 because the absolute value is 8.9 which is greater than 5.6 .</h2>

If a pool is 4 m wide and 16 m diagonally across, how long is the pool? (Pyth. Theorem)

alukav5142 [94]

Answer:

$L=4\sqrt{15}\ m$

$L=15.49\ m$

Step-by-step explanation:

we know that

Applying the Pythagorean Theorem in the rectangular pool

$d^2=L^2+W^2$

where

d is the diagonal of the pool

L is the length of the pool

W is the wide of the pool

we have

$d=16\ m\\W=4\ m$

substitute the given values

$16^2=L^2+4^2$

solve for L

$L^2=16^2-4^2\\L^2=240\\L=\sqrt{240}\ m$

simplify

$L=4\sqrt{15}\ m$

$L=15.49\ m$

The frame around a picture with an area of 192 square inches, measures x inches across. The length of the picture with its frame

prisoha [69]

Okay so
area of picture= 192cm
area of frame= 40×24=960

960÷ 192= 5

Therefore the picture is 1/5 of the frame.
Length of picture = 1/5 × 40 = 8cm
Width of picture = 192/8 = 24

The dimensions of the picture are then 8cm × 24 cm.

1.consider the function

marin [14]

Function transformation involves changing the form of a function

The transformation from f(x) to g(x) is a horizontal shift 3 units left, followed by a vertical stretch by a factor of 4
The x and y intercepts are -0.67 and 1.91, respectively.
The behavior of g(x) is that, g(x) approaches infinity, as x approaches infinity.

The functions are given as:

$\mathbf{f(x) = log3x}$
